Activities in Cognite Data Fusion (CDF) represent tasks, events, or operations that happen over a period of time in your industrial environment. They provide a structured way to track work, maintenance, inspections, and other time-based activities, connecting planned and executed work with your physical assets and operational data.Turn on Activity to visualize and contextualize time series data with these operational events in your chart. Activities appear as vertical bars in the chart, providing visual reference to help you correlate time series behavior with relevant operational activities such as maintenance work, inspections, or production events.
You have time series read access rights to view Charts and the relevant data.
To add activities to a chart:
1
Add time series
Select + Add data > Add time series. Search and select the time series you want to visualize.
2
Select activities
In the Category dropdown, select Activity, and then select the activities you want to visualize.
Once selected, the Activity layer will turn on automatically.
The Asset filter applies automatically based on the time series the assets belong to in the chart. You can clear or add filters based on your preferences.
Activities appear as vertical blue bars on the Activity layer. These bars help you visually correlate time series with relevant activities. Activities that start before or end after the selected time range are also shown, so you don’t miss activities that overlap the edges of your view. The bars have varying levels of transparency to distinguish overlapping activities and keep multi-layer views readable.To work with activities:
1
View activity details
Click an activity bar to view details such as start and end times, a description, and the asset the activity is tied to. Click View details to see full information about the activity. The date range on the Activity page matches the time range set in your chart, including extended activities.
2
Pin an activity
Click the pin icon to keep the activity highlighted while you compare it with other activities.
3
Hover to highlight
In the search panel, open the Activity category and hover over an activity to highlight the matching bar in the chart. This works for activities already added to the chart. If an activity is already pinned, it can appear shadowed while you hover a different activity.
Time series monitoring jobs send emails for any breaches to the thresholds you set. If there are several breaches within the minimum duration period, you’ll only receive one email for the period.We recommend that you set a minimum duration of 5 minutes to limit the number of email alerts you receive. The minimum expected data point frequency is 1 minute. If the data points have a lower frequency, alerts may not trigger as expected.
If a chart contains more than 100,000 data points, Charts summarizes the data points to make the data easier to view. The aggregated data is shaded and shows the minimum and maximum values of the aggregated data range. Zoom in to view individual data points.
